Rude service from their sales team

Poor service and communication skills received from Lethabo in their parts department. I had ordered a new battery from her and was promised to receive the battery the following day in the afternoon, the day of collection I called in to confirm if the battery had arrived and the lady said no, and I had asked her to notify me as soon as it arrived as it was an urgent order, so I then asked her why did you not make an effort in informing me that the battery has not arrived and there will be a delay so that I can also know how to move forward, she just apologised for the lack of communication and promised I would receive it the next morning around 10am as thats when the driver with their orders normally arrives. I started calling from 10:45am trying to get through to Lethabo in parts only to be sent back and forth between her and the reception, when I do get to parts she puts me on hold until she hangs up. My call was attended to at 11:05am and upon questioning the location of the battery I was told it had arrived, and I asked her why did she not bother informing me that it had arrived and I now have to struggle getting ahold of her whilst she had promised to call me as soon as it arrived in the morning, she then responded by telling me that im being difficult. I asked to be put through to her manager and she refused to give me the managers contact aswell.
